Default Sc400 idle issues

So i recently bought a clean 1992 sc400 for a low low price of $700 talk about a steal i brought it home no problems but this morning i cranked it and idleing would bounce from 2000 rpms down to 1000 rpms and back up again it had recently been rebuilt and i wondering if the fella knew what he was doing ive read and found out it could be the iacv, or the tps sensor is their a certain way to put the tps sensor on? Like a certain installation method?

Default Throttle Body & Idle control valve needed for 1995 SC 400

Parts have been discontinued for years. Looking for used ones with lowest miles possible.
